3 Credit(s)
Statistical inferences including estimation, confidence intervals, and tests of hypotheses for means, standard deviations, and proportions: analysis of variance; regression analysis; chi-square; business applications. Students will develop a basic competency in using a computer spreadsheet and/or the graphing calculator to perform statistical calculations.

Student Learning Outcomes for Course

Outcomes	Assessments – How it is met & When it is met

Homework
Media Assignment – to be completed through online component outside of class time
Study Plan – to be completed through online component and required to complete before each test outside of class time
Chapter Activity – Located at the end of the indicated chapter. For example, activity 8.1, is at the end of chapter 8
Statistics in Action Discussion Post (at the beginning of the indicated chapter) – Form groups of 3 or 4 students. Each student will write two (2) questions for the other group members to answer. Then each of the other group members will answer one of the two questions. The question writer will respond to each of the other students’ answers indicating if the student is correct or providing an explanation for the student’s answer. Each student is graded on the two questions they formulate and the response they provide to the students’ answers of their questions. Students are not being graded on the answer they provide to the question writer. At any point during the discussion, please reach out to the instructor with any questions.
